This invention relates to certain pyrazole derivatives, their N-oxides and salts, and to mixtures and compositions comprising such pyrazole derivatives and methods for using such pyrazole derivatives and their mixtures and compositions as fungicides.
The control of plant diseases caused by fungal plant pathogens is extremely important in achieving high crop efficiency. Plant disease damage to ornamental, vegetable, field, cereal and fruit crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. In addition to often being highly destructive, plant diseases can be difficult to control and may develop resistance to commercial fungicides. Many products are commercially available for these purposes, but the need continues for new fungicidal compounds which are more effective, less costly, less toxic, environmentally safer or have different sites of action. Besides introduction of new fungicides, combinations of fungicides are often used to facilitate disease control, to broaden spectrum of control and to retard resistance development. Furthermore, certain rare combinations of fungicides demonstrate a greater-than-additive (i.e. synergistic) effect to provide commercially important levels of plant disease control. The advantages of particular fungicide combinations are recognized in the art to vary, depending on such factors as the particular plant species and plant disease to be treated, and whether the plants are treated before or after infection with the fungal plant pathogen. Accordingly new advantageous combinations are needed to provide a variety of options to best satisfy particular plant disease control needs. Such combinations have now been discovered. JP08208620 discloses N-phenyl-pyrazolylamine derivatives as insecticides, herbicides and fungicides; however the fungicidal pyrazoles of the present invention and their mixtures are not disclosed in this publication.
This invention relates to a fungicidal composition (i.e. combination) comprising (a) at least one compound selected from the compounds of Formula 1 (including all stereoisomers), N-oxides, and salts thereof:
##STR00002##
wherein
X is CHOH, O or NH;
R1 is halogen or methyl;
R2 is H, cyano, halogen or C1-C2 alkoxy;
R3 is H, halogen or methyl;
R4 is halogen;
R5 is H, cyano, halogen or C1-C2 alkoxy; and
R6 is H or halogen; and
(b) at least one additional fungicidal compound.
This invention also relates to a composition comprising: (a) at least one compound selected from the compounds of Formula 1 described above, N-oxides, and salts thereof; and at least one invertebrate pest control compound or agent.
This invention also relates to a composition comprising one of the aforesaid compositions comprising component (a) and at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents.
This invention also relates to a method for controlling plant diseases caused by fungal plant pathogens comprising applying to the plant or portion thereof, or to the plant seed, a fungicidally effective amount of one of the aforesaid compositions.
The aforedescribed method can also be described as a method for protecting a plant or plant seed from diseases caused by fungal pathogens comprising applying a fungicidally effective amount of one of the aforesaid compositions to the plant (or portion thereof) or plant seed (directly or through the environment (e.g., growing medium) of the plant or plant seed).
This invention also relates to a compound of Formula 1 described above, or an N-oxide or salt thereof. This invention further relates to a fungicidal composition comprising a compound of Formula 1, or an N-oxide or salt thereof, and at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents. This invention also further relates to a method for protecting a plant or plant seed from diseases caused by fungal pathogens comprising a fungicidally effective amount of a compound of Formula 1, or an N-oxide or salt thereof, to the plant or plant seed.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method.
The transitional phrase “consisting of” excludes any element, step, or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.
The transitional phrase “consisting essentially of” is used to define a composition or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.
Where applicants have defined an invention or a portion thereof with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such an invention using the terms “consisting essentially of” or “consisting of”.
Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Also, the indefinite articles “a” and “an” preceding an element or component of the invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.
As referred to in the present disclosure and claims, “plant” includes members of Kingdom Plantae, particularly seed plants (Spermatopsida), at all life stages, including young plants (e.g., germinating seeds developing into seedlings) and mature, reproductive stages (e.g., plants producing flowers and seeds). Portions of plants include geotropic members typically growing beneath the surface of the growing medium (e.g., soil), such as roots, tubers, bulbs and corms, and also members growing above the growing medium, such as foliage (including stems and leaves), flowers, fruits and seeds.
As referred to herein, the term “seedling”, used either alone or in a combination of words means a young plant developing from the embryo of a seed.
In the above recitations, the term “alkoxy” includes, for example, methoxy and ethoxy. The term “halogen” includes fluorine, chlorine, bromine or iodine.
The total number of carbon atoms in a substituent group is indicated by the “Ci-Cj” prefix where i and j are numbers from 1 to 2.
Compounds relevant to the compositions and methods of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. The compounds in the compositions of this invention may be present as a mixture of stereoisomers, individual stereoisomers or as an optically active form.
Synthetic methods for the preparation of N-oxides of heterocycles such as pyrazoles are very well known by one skilled in the art including the oxidation of heterocycles with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M. R. Grimmett and B. R. T. Keene in Advances in Heterocyclic Chemistry, vol. 43, pp 149-161, A. R. Katritzky, Ed., Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390-392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.
One skilled in the art recognizes that because in the environment and under physiological conditions salts of chemical compounds are in equilibrium with their corresponding nonsalt forms, salts share the biological utility of the nonsalt forms. Thus a wide variety of salts of the compounds of Formula 1 alone and in mixtures are useful for control of plant diseases caused by fungal plant pathogens (i.e. are agriculturally suitable). The salts of the compounds of Formula 1 include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. Accordingly, the present invention relates to mixtures of compounds selected from Formula 1, N-oxides and agriculturally suitable salts thereof.
Compounds selected from Formula 1, stereoisomers, tautomers, N-oxides, and salts thereof, typically exist in more than one form, and Formula 1 thus includes all crystalline and non-crystalline forms of the compounds that Formula 1 represents. Non-crystalline forms include embodiments which are solids such as waxes and gums as well as embodiments which are liquids such as solutions and melts. Crystalline forms include embodiments which represent essentially a single crystal type and embodiments which represent a mixture of polymorphs (i.e. different crystalline types). The term “polymorph” refers to a particular crystalline form of a chemical compound that can crystallize in different crystalline forms, these forms having different arrangements and/or conformations of the molecules in the crystal lattice. Although polymorphs can have the same chemical composition, they can also differ in composition due the presence or absence of co-crystallized water or other molecules, which can be weakly or strongly bound in the lattice. Polymorphs can differ in such chemical, physical and biological properties as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspensibility, dissolution rate and biological availability. One skilled in the art will appreciate that a polymorph of a compound represented by Formula 1 can exhibit beneficial effects (e.g., suitability for preparation of useful formulations, improved biological performance) relative to another polymorph or a mixture of polymorphs of the same compound represented by Formula 1. Preparation and isolation of a particular polymorph of a compound represented by Formula 1 can be achieved by methods known to those skilled in the art including, for example, crystallization using selected solvents and temperatures.
As described in the Summary of the Invention, an aspect of the present invention is directed at a composition comprising (a) at least one compound selected from Formula 1, N-oxides, and salts thereof, with (b) at least one additional fungicidal compound. More particularly, Component (b) is selected from the group consisting of
Of note are embodiments wherein component (b) comprises at least one fungicidal compound from each of two different groups selected from (b1) through (b46).
“Methyl benzimidazole carbamate (MBC) fungicides (b1)” (FRAC (Fungicide Resistance Action Committee) code 1) inhibit mitosis by binding to β-tubulin during microtubule assembly. Inhibition of microtubule assembly can disrupt cell division, transport within the cell and cell structure. Methyl benzimidazole carbamate fungicides include benzimidazole and thiophanate fungicides. The benzimidazoles include benomyl, carbendazim, fuberidazole and thiabendazole. The thiophanates include thiophanate and thiophanate-methyl.

“Demethylation inhibitor (DMI) fungicides (b3)” (FRAC code 3) inhibit C14-demethylase which plays a role in sterol production. Sterols, such as ergosterol, are needed for membrane structure and function, making them essential for the development of functional cell walls. Therefore, exposure to these fungicides result in abnormal growth and eventually death of sensitive fungi. DMI fungicides are divided between several chemical classes: azoles (including triazoles and imidazoles), pyrimidines, piperazines and pyridines. The triazoles include azaconazole, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole (including diniconazole-M), epoxiconazole, etaconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imibenconazole, ipconazole, metconazole, myclobutanil, penconazole, propiconazole, prothioconazole, quinconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole and uniconazole.

The piperazines include triforine. The pyridines include buthiobate and pyrifenox. Biochemical investigations have shown that all of the above mentioned fungicides are DMI fungicides as described by K. H. Kuck et al. in Modern Selective Fungicides—Properties, Applications and Mechanisms of Action, H. Lyr (Ed.), Gustav Fischer Verlag: New York, 1995, 205-258.
“Phenylamide fungicides (b4)” (FRAC code 4) are specific inhibitors of RNA polymerase in Oomycete fungi. Sensitive fungi exposed to these fungicides show a reduced capacity to incorporate uridine into rRNA. Growth and development in sensitive fungi is prevented by exposure to this class of fungicide. Phenylamide fungicides include acylalanine, oxazolidinone and butyrolactone fungicides. The acylalanines include benalaxyl, benalaxyl-M, furalaxyl, metalaxyl, metalaxyl-M (also known as mefenoxam). The oxazolidinones include oxadixyl. The butyrolactones include ofurace.
“Amine/morpholine fungicides (b5)” (FRAC code 5) inhibit two target sites within the sterol biosynthetic pathway, Δ8→Δ7 isomerase and Δ14 reductase. Sterols, such as ergosterol, are needed for membrane structure and function, making them essential for the development of functional cell walls. Therefore, exposure to these fungicides results in abnormal growth and eventually death of sensitive fungi. Amine/morpholine fungicides (also known as non-DMI sterol biosynthesis inhibitors) include morpholine, piperidine and spiroketal-amine fungicides. The morpholines include aldimorph, dodemorph, fenpropimorph, tridemorph and trimorphamide. The piperidines include fenpropidin and piperalin. The spiroketal-amines include spiroxamine.

“Carboxamide fungicides (b7)” (FRAC code 7) inhibit Complex II (succinate dehydrogenase) fungal respiration by disrupting a key enzyme in the Krebs Cycle (TCA cycle) named succinate dehydrogenase. Inhibiting respiration prevents the fungus from making ATP, and thus inhibits growth and reproduction. Carboxamide fungicides include benzamide, furan carboxamide, oxathiin carboxamide, thiazole carboxamide, pyrazole carboxamide and pyridine carboxamide. The benzamides include benodanil, flutolanil and mepronil. The furan carboxamides include fenfuram. The oxathiin carboxamides include carboxin and oxycarboxin. The thiazole carboxamides include thifluzamide. The pyrazole carboxamides include bixafen, furametpyr, isopyrazam, fluxapyroxad, penthiopyrad, sedaxane (N-[2-(1S,2R)-[1,1′-bicyclopropyl]-2-ylphenyl]-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide) and penflufen (N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide) (PCT Patent Publication WO 2003/010149). The pyridine carboxamides include boscalid.
“Hydroxy(2-amino-)pyrimidine fungicides (b8)” (FRAC code 8) inhibit nucleic acid synthesis by interfering with adenosine deaminase. Examples include bupirimate, dimethirimol and ethirimol.
“Anilinopyrimidine fungicides (b9)” (FRAC code 9) are proposed to inhibit biosynthesis of the amino acid methionine and to disrupt the secretion of hydrolytic enzymes that lyse plant cells during infection. Examples include cyprodinil, mepanipyrim and pyrimethanil.
“N-Phenyl carbamate fungicides (b10)” (FRAC code 10) inhibit mitosis by binding to β-tubulin and disrupting microtubule assembly. Inhibition of microtubule assembly can disrupt cell division, transport within the cell and cell structure. Examples include diethofencarb.
“Quinone outside inhibitor (QoI) fungicides (b11)” (FRAC code 11) inhibit Complex III mitochondrial respiration in fungi by affecting ubiquinol oxidase. Oxidation of ubiquinol is blocked at the “quinone outside” (Qo) site of the cytochrome bc1 complex, which is located in the inner mitochondrial membrane of fungi. Inhibiting mitochondrial respiration prevents normal fungal growth and development. Quinone outside inhibitor fungicides include methoxyacrylate, methoxycarbamate, oximinoacetate, oximinoacetamide and dihydrodioxazine fungicides (collectively also known as strobilurin fungicides), and oxazolidinedione, imidazolinone and benzylcarbamate fungicides. The methoxyacrylates include azoxystrobin, enestroburin (SYP-Z071) and picoxystrobin. The methoxycarbamates include pyraclostrobin and pyrametostrobin. The oximinoacetates include kresoxim-methyl, pyraoxystrobin and trifloxystrobin.

They have been shown to interfere with germination and/or appressorium formation in fungi that cause powdery mildew diseases. Quinoxyfen is an example of this class of fungicide.
“Lipid peroxidation inhibitor fungicides (b14)” (FRAC code 14) are proposed to inhibit lipid peroxidation which affects membrane synthesis in fungi. Members of this class, such as etridiazole, may also affect other biological processes such as respiration and melanin biosynthesis. Lipid peroxidation fungicides include aromatic carbon and 1,2,4-thiadiazole fungicides. The aromatic carbons include biphenyl, chloroneb, dicloran, quintozene, tecnazene and tolclofos-methyl. The 1,2,4-thiadiazoles include etridiazole.
“Melanin biosynthesis inhibitors-reductase (MBI-R) fungicides (b15)” (FRAC code 16.1) inhibit the naphthal reduction step in melanin biosynthesis. Melanin is required for host plant infection by some fungi. Melanin biosynthesis inhibitors-reductase fungicides include isobenzofuranone, pyrroloquinolinone and triazolobenzothiazole fungicides. The isobenzofuranones include fthalide. The pyrroloquinolinones include pyroquilon. The triazolobenzothiazoles include tricyclazole.
“Melanin biosynthesis inhibitors-dehydratase (MBI-D) fungicides (b16)” (FRAC code 16.2) inhibit scytalone dehydratase in melanin biosynthesis.

The cyclopropanecarboxamides include carpropamid. The carboxamides include diclocymet. The propionamides include fenoxanil.
“Hydroxyanilide fungicides (b17)” (FRAC code 17) inhibit C4-demethylase which plays a role in sterol production. Examples include fenhexamid.
“Squalene-epoxidase inhibitor fungicides (b18)” (FRAC code 18) inhibit squalene-epoxidase in ergosterol biosynthesis pathway. Sterols such as ergosterol are needed for membrane structure and function, making them essential for the development of functional cell walls. Therefore exposure to these fungicides result in abnormal growth and eventually death of sensitive fungi. Squalene-epoxidase inhibitor fungicides include thiocarbamate and allylamine fungicides. The thiocarbamates include pyributicarb. The allylamines include naftifine and terbinafine.
“Polyoxin fungicides (b19)” (FRAC code 19) inhibit chitin synthase. Examples include polyoxin.
“Phenylurea fungicides (b20)” (FRAC code 20) are proposed to affect cell division. Examples include pencycuron.
“Quinone inside inhibitor (QiI) fungicides (b21)” (FRAC code 21) inhibit Complex III mitochondrial respiration in fungi by affecting ubiquinol reductase. Reduction of ubiquinol is blocked at the “quinone inside” (Qi) site of the cytochrome bc1 complex, which is located in the inner mitochondrial membrane of fungi. Inhibiting mitochondrial respiration prevents normal fungal growth and development. Quinone inside inhibitor fungicides include cyanoimidazole and sulfamoyltriazole fungicides. The cyanoimidazoles include cyazofamid. The sulfamoyltriazoles include amisulbrom.
“Benzamide fungicides (b22)” (FRAC code 22) inhibit mitosis by binding to β-tubulin and disrupting microtubule assembly. Inhibition of microtubule assembly can disrupt cell division, transport within the cell and cell structure. Examples include zoxamide.

##STR00004##
As is shown in Scheme 2, compounds of Formula 1 can be prepared by the reaction of compounds of Formula 4 (i.e. 5-aminopyrazoles for X being NH, or 5-hydroxypyrazoles (5-pyrazolones) for X being O, with aromatic compounds of Formula 5 containing a leaving group G (i.e. halogen or (halo)alkylsulfonate), optionally in the presence of a metal catalyst, and generally in the presence of a base and a polar aprotic solvent such as N,N-dimethylformamide or dimethyl sulfoxide. For example, compounds of Formula 5 wherein the benzene ring contains electron-withdrawing substituents react by direct displacement of the leaving group G from the ring to provide compounds of Formula 1. The method of Scheme 2 is illustrated by Step D of Synthesis Example 6. Compounds of Formula 5 are commercially available or their preparation is known in the art.
##STR00005##
For reactions according to the method of Scheme 2 of a compound of Formula 4 wherein X is O or NH with a compound of Formula 5 wherein the aromatic ring lacks sufficiently electron-withdrawing substituents, or to improve reaction rate, yield or product purity, the use of a metal catalyst (e.g., metal or metal salt) in amounts ranging from catalytic up to superstoichiometric can facilitate the desired reaction. Typically for these conditions, G is Br or I or a sulfonate such as OS(O)2CF3 or OS(O)2(CF2)3CF3. For example, copper salt complexes (e.g., CuI with N,N′-dimethylethylenediamine, proline or bipyridyl), palladium complexes (e.g., tris(dibenzylideneacetone)dipalladium(0)) or palladium salts (e.g., palladium acetate) with ligands such as 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (i.e. “Xantphos”), 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (i.e. “Xphos”) or 2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (i.e. “BINAP”), in the presence of a base such as potassium carbonate, cesium carbonate, sodium phenoxide or sodium tert-butoxide, in a solvent such as N,N-dimethylformamide, 1,2-dimethoxyethane, dimethyl sulfoxide, 1,4-dioxane or toluene, optionally mixed with alcohols such as ethanol, can be used.

For example, addition of tert-butyl nitrite to a solution of a 5-aminopyrazole of Formula 4a in the presence of CuBr2 in a solvent such as acetonitrile provides the corresponding 5-bromopyrazole of Formula 6. Likewise, a 5-aminopyrazole of Formula 4a can be converted to a diazonium salt and then to a corresponding 5-halopyrazole of Formula 6 by treatment with sodium nitrite in solvents such as water, acetic acid or trifluoroacetic acid, in the presence of a mineral acid typically containing the same halide atom (such as aqueous HI solution for G being I), followed by treatment with the corresponding copper(I) or copper(II) salt according to general procedures well known to those skilled in the art. The method of Scheme 4 is illustrated by Step B of Synthesis Example 1 and Step D of Synthesis Example 2.

##STR00009##
As shown in Scheme 7, compounds of Formula 1 can be prepared by reaction of 4-bromo or iodo pyrazoles of Formula 10 wherein X is O or NH with organometallic compounds of Formula 11 under transition-metal-catalyzed cross-coupling reaction conditions. Reaction of a 4-bromo or iodo pyrazole of Formula 10 with a boronic acid, trialkyltin, zinc or organomagnesium reagent of Formula 11 in the presence of a palladium or nickel catalyst having appropriate ligands (e.g., triphenylphosphine (PPh3), dibenzylideneacetone (dba), dicyclohexyl(2′,6′-dimethoxy[1,1′-biphenyl]-2-yl)phosphine (SPhos)) and a base, if needed, affords the corresponding compound of Formula 1.

This method of Scheme 12 is illustrated by Synthesis Example 5. Alternatively, compounds of Formula 1b can be prepared by reduction of ketones of Formula 19 using standard methods well known in the art (e.g., sodium borohydride in methanol or methanol). Ketones of Formula 19 can be prepared by reaction of the same metalated pyrazole derivative of the compound of Formula 6 with carbon electrophiles of Formula 17 or 18. Reaction temperatures can range from −90° C. to the boiling point of the reaction solvent; temperatures of −78° C. to ambient temperature are generally preferred, with temperatures of −78 to −10° C. preferred when an alkyllithium reagent is used, and −20° C. to ambient temperature preferred with use of alkylmagnesium reagents.

A second metallic component, such as zinc chloride, zinc bromide or a monovalent copper salt, such as copper(I) iodide or copper(I) cyanide, can advantageously be added before the electrophile in cases in which the electrophile is a compound of Formula 18.

##STR00018##
In a manner analogous to the method of Scheme 15, compounds of Formula 2 wherein X is NH can be similarly prepared by condensing compounds of Formula 23 with hydrazine. This method is described in Chemistry of Heterocyclic Compounds 2005, 41(1), 105-110.
As shown in Scheme 16, compounds of Formula 23 (wherein, R32 is H or lower alkyl such as CH3, CH2CH3 or (CH2)2CH3) can be prepared by reaction of corresponding ketene dithioacetal compounds of Formula 24 with compounds of Formula 7 optionally in the presence of a base, such as sodium hydride or ethylmagnesium chloride, in solvents such as toluene, tetrahydrofuran or dimethoxymethane, at temperatures ranging from −10° C. to the boiling point of the solvent. See, for example, J. Heterocycl. Chem. 1975, 12(1), 139. Methods useful for preparing compounds of Formula 24 are known in the art.
##STR00019##
As shown in Scheme 17, compounds of Formula 23a (i.e. tautomer of Formula 23 wherein R32 is H) can be prepared by reaction of corresponding isothiocyanate compounds of Formula 25 with arylacetone compounds of Formula 26; see, for example, Zhurnal Organicheskoi Khimii 1982, 18(12), 2501. Bases useful for this reaction include sodium hydride, alkoxide bases (e.g., potassium tert-butoxide or sodium ethoxide), potassium hydroxide, sodium hydroxide, potassium carbonate, or amine bases (e.g., triethylamine or N,N-diisopropylethylamine). A variety of solvents are useful, such as tetrahydrofuran, ether, toluene, N,N-dimethylformamide, alcohols (e.g., ethanol), esters (e.g., ethyl acetate or isopropyl acetate), or mixtures thereof. Solvents are chosen for compatibility with the base selected, as is well-known in the art. Reaction temperatures can range from −78° C. to the boiling point of the solvent.

Ketothioamides of Formula 23a can be also be prepared by allowing the corresponding ketoamides to react with sulfurizing agents such as Lawesson's reagent or P2S5; see, for example, Helv. Chim. Act. 1998, 81(7), 1207.
It is recognized by one skilled in the art that various functional groups can be converted into others to provide different compounds of Formula 1. For example, intermediates for the preparation of compounds of Formula 1 may contain aromatic nitro groups, which can be reduced to amino groups, and then be converted via reactions well known in the art such as the Sandmeyer reaction, to various halides, providing compounds of Formula 1. By similar known reactions, aromatic amines (anilines) can be converted via diazonium salts to phenols, which can then be alkylated to prepare compounds of Formula 1 with alkoxy substituents. Likewise, aromatic halides such as bromides or iodides prepared via the Sandmeyer reaction can react with alcohols under copper-catalyzed conditions, such as the Ullmann reaction or known modifications thereof, to provide compounds of Formula 1 that contain alkoxy substituents. Additionally, some halogen groups, such as fluorine or chlorine, can be displaced with alcohols under basic conditions to provide compounds of Formula 1 containing the corresponding alkoxy substituents.
The above reactions can also in many cases be performed in alternate sequence, such as the preparation of 1H pyrazoles for use in the reaction in Scheme 2 by reactions illustrated later for the general preparation of substituted pyrazoles.
It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula 1. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula 1. One skilled in the art will also recognize that compounds of Formula 1 and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Parts and percentages for chromatographic solvent mixtures are by volume unless otherwise indicated. 1H NMR spectra are reported in ppm downfield from tetramethylsilane in CDCl3 unless otherwise noted; “s” means singlet, “m” means multiplet, “br s” means broad singlet. Mass spectra (MS) are reported as the molecular weight of the highest isotopic abundance parent ion (M+1) formed by addition of H+ (molecular weight of 1) to the molecule, observed by mass spectrometry using atmospheric pressure chemical ionization (AP+) where “amu” stands for atomic mass units. The presence of molecular ions containing one or more higher atomic weight isotopes of lower abundance (e.g., 37Cl, 81Br) is not reported. “LC/MS” refers the combination of physical separation of chemical compounds by liquid chromatography and mass analysis of the separated compounds by mass spectrometry.

Analysis of the combined solids by LC/MS showed a primary component of mass 242 (AP+) and a minor component, eluting later by reverse-phase LC, also having a mass of 242 (AP+), thus being a regioisomer of the title compound. The apparent ratio of components was 94:6.

R4 is F, R5 is H, R6 is H, and X is NH.
The present disclosure also includes Tables 2 through 180, each of which is constructed the same as Table 1 above, except that the row heading in Table 1 (i.e. “R4 is F, R5 is H, R6 is H, and X is NH.”) is replaced with the respective row heading shown below. For Example, in Table 2 the row heading is “R4 is F, R5 is H, R6 is F, and X is NH.”, and R4, R5, and R6 are as defined in Table 1 above. Thus, the first entry in Table 2 specifically discloses 4-(2,6-difluorophenyl)-N-(2-fluorophenyl)-1,3-dimethyl-1H-pyrazol-5-amine).

Formulation/Utility
A compound selected from compounds of Formula 1, N-oxides, and salts thereof, or a mixture (i.e. composition) comprising the compound with at least one additional fungicidal compound as described in the Summary of the Invention, will generally be used to provide fungicidal active ingredients in further compositions, i.e. formulations, with at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents, which serves as a carrier. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredients, mode of application and environmental factors such as soil type, moisture and temperature.
The mixtures of component (a) (i.e. at least one compound of Formula 1, N-oxides, or salts thereof) with component (b) (e.g., selected from (b1) to (b46) and salts thereof as described above) and/or one or more other biologically active compound or agent (i.e. insecticides, other fungicides, nematocides, acaricides, herbicides and other biological agents) can be formulated in a number of ways, including:
Useful formulations include both liquid and solid compositions. Liquid compositions include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like, which optionally can be thickened into gels. The general types of aqueous liquid compositions are soluble concentrate, suspension concentrate, capsule suspension, concentrated emulsion, microemulsion and suspo-emulsion. The general types of nonaqueous liquid compositions are emulsifiable concentrate, microemulsifiable concentrate, dispersible concentrate and oil dispersion.
The general types of solid compositions are dusts, powders, granules, pellets, prills, pastilles, tablets, filled films (including seed coatings) and the like, which can be water-dispersible (“wettable”) or water-soluble. Films and coatings formed from film-forming solutions or flowable suspensions are particularly useful for seed treatment. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or “overcoated”). Encapsulation can control or delay release of the active ingredient. An emulsifiable granule combines the advantages of both an emulsifiable concentrate formulation and a dry granular formulation. High-strength compositions are primarily used as intermediates for further formulation.
Of note is a composition embodiment wherein granules of a solid composition comprising a compound of Formula 1 (or an N-oxide or salt thereof) is mixed with granules of a solid composition comprising component (b). These mixtures can be further mixed with granules comprising additional agricultural protectants. Alternatively, two or more agricultural protectants (e.g., a component (a) (Formula 1) compound, a component (b) compound, an agricultural protectant other than component (a) or (b)) can be combined in the solid composition of one set of granules, which is then mixed with one or more sets of granules of solid compositions comprising one or more additional agricultural protectants. These granule mixtures can be in accordance with the general granule mixture disclosure of PCT Patent Publication WO 94/24861 or more preferably the homogeneous granule mixture teaching of U.S. Pat. No. 6,022,552.
Sprayable formulations are typically extended in a suitable medium before spraying. Such liquid and solid formulations are formulated to be readily diluted in the spray medium, usually water. Spray volumes can range from about from about one to several thousand liters per hectare, but more typically are in the range from about ten to several hundred liters per hectare. Sprayable formulations can be tank mixed with water or another suitable medium for foliar treatment by aerial or ground application, or for application to the growing medium of the plant. Liquid and dry formulations can be metered directly into drip irrigation systems or metered into the furrow during planting. Liquid and solid formulations can be applied onto seeds of crops and other desirable vegetation as seed treatments before planting to protect developing roots and other subterranean plant parts and/or foliage through systemic uptake.
The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, gypsum, cellulose, titanium dioxide, zinc oxide, starch, dextrin, sugars (e.g., lactose, sucrose), silica, talc, mica, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Typical solid diluents are described in Watkins et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, N.J.
Liquid diluents include, for example, water, N,N-dimethylalkanamides (e.g., N,N-dimethylformamide), limonene, dimethyl sulfoxide, N-alkylpyrrolidones (e.g., N-methylpyrrolidinone), ethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, propylene carbonate, butylene carbonate, paraffins (e.g., white mineral oils, normal paraffins, isoparaffins), alkylbenzenes, alkylnaphthalenes, glycerine, glycerol triacetate, sorbitol, triacetin, aromatic hydrocarbons, dearomatized aliphatics, alkylbenzenes, alkylnaphthalenes, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4-methyl-2-pentanone, acetates such as isoamyl acetate, hexyl acetate, heptyl acetate, octyl acetate, nonyl acetate, tridecyl acetate and isobornyl acetate, other esters such as alkylated lactate esters, dibasic esters and γ-butyrolactone, and alcohols, which can be linear, branched, saturated or unsaturated, such as methanol, ethanol, n-propanol, isopropyl alcohol, n-butanol, isobutyl alcohol, n-hexanol, 2-ethylhexanol, n-octanol, decanol, isodecyl alcohol, isooctadecanol, cetyl alcohol, lauryl alcohol, tridecyl alcohol, oleyl alcohol, cyclohexanol, tetrahydrofurfuryl alcohol, diacetone alcohol and benzyl alcohol. Liquid diluents also include glycerol esters of saturated and unsaturated fatty acids (typically C6-C22), such as plant seed and fruit oils (e.g., oils of olive, castor, linseed, sesame, corn (maize), peanut, sunflower, grapeseed, safflower, cottonseed, soybean, rapeseed, coconut and palm kernel), animal-sourced fats (e.g., beef tallow, pork tallow, lard, cod liver oil, fish oil), and mixtures thereof. Liquid diluents also include alkylated fatty acids (e.g., methylated, ethylated, butylated) wherein the fatty acids may be obtained by hydrolysis of glycerol esters from plant and animal sources, and can be purified by distillation. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950.
The solid and liquid compositions of the present invention often include one or more surfactants. When added to a liquid, surfactants (also known as “surface-active agents”) generally modify, most often reduce, the surface tension of the liquid. Depending on the nature of the hydrophilic and lipophilic groups in a surfactant molecule, surfactants can be useful as wetting agents, dispersants, emulsifiers or defoaming agents.
Surfactants can be classified as nonionic, anionic or cationic. Nonionic surfactants useful for the present compositions include, but are not limited to: alcohol alkoxylates such as alcohol alkoxylates based on natural and synthetic alcohols (which may be branched or linear) and prepared from the alcohols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof; amine ethoxylates, alkanolamides and ethoxylated alkanolamides; alkoxylated triglycerides such as ethoxylated soybean, castor and rapeseed oils; alkylphenol alkoxylates such as octylphenol ethoxylates, nonylphenol ethoxylates, dinonyl phenol ethoxylates and dodecyl phenol ethoxylates (prepared from the phenols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); block polymers prepared from ethylene oxide or propylene oxide and reverse block polymers where the terminal blocks are prepared from propylene oxide; ethoxylated fatty acids; ethoxylated fatty esters and oils; ethoxylated methyl esters; ethoxylated tristyrylphenol (including those prepared from ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); fatty acid esters, glycerol esters, lanolin-based derivatives, polyethoxylate esters such as polyethoxylated sorbitan fatty acid esters, polyethoxylated sorbitol fatty acid esters and polyethoxylated glycerol fatty acid esters; other sorbitan derivatives such as sorbitan esters; polymeric surfactants such as random copolymers, block copolymers, alkyd peg (polyethylene glycol) resins, graft or comb polymers and star polymers; polyethylene glycols (pegs); polyethylene glycol fatty acid esters; silicone-based surfactants; and sugar-derivatives such as sucrose esters, alkyl polyglycosides and alkyl polysaccharides.

Compositions of this invention may also contain formulation auxiliaries and additives, known to those skilled in the art as formulation aids (some of which may be considered to also function as solid diluents, liquid diluents or surfactants). Such formulation auxiliaries and additives may control: pH (buffers), foaming during processing (antifoams such polyorganosiloxanes), sedimentation of active ingredients (suspending agents), viscosity (thixotropic thickeners), in-container microbial growth (antimicrobials), product freezing (antifreezes), color (dyes/pigment dispersions), wash-off (film formers or stickers), evaporation (evaporation retardants), and other formulation attributes. Film formers include, for example, polyvinyl acetates, polyvinyl acetate copolymers, polyvinylpyrrolidone-vinyl acetate copolymer, polyvinyl alcohols, polyvinyl alcohol copolymers and waxes. Examples of formulation auxiliaries and additives include those listed in McCutcheon's Volume 2: Functional Materials, annual International and North American editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; and PCT Publication WO 03/024222.
The compounds of Formula 1 and any other active ingredients are typically incorporated into the present compositions by dissolving the active ingredient in a solvent or by grinding in a liquid or dry diluent. Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. If the solvent of a liquid composition intended for use as an emulsifiable concentrate is water-immiscible, an emulsifier is typically added to emulsify the active-containing solvent upon dilution with water. Active ingredient slurries, with particle diameters of up to 2,000 μm can be wet milled using media mills to obtain particles with average diameters below 3 μm. Aqueous slurries can be made into finished suspension concentrates (see, for example, U.S. Pat. No. 3,060,084) or further processed by spray drying to form water-dispersible granules. Dry formulations usually require dry milling processes, which produce average particle diameters in the 2 to 10 μm range. Dusts and powders can be prepared by blending and usually grinding (such as with a hammer mill or fluid-energy mill). Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, “Agglomeration”, Chemical Engineering, Dec. 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. Pat. No. 4,144,050, U.S. Pat. No. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. Pat. No. 5,180,587, U.S. Pat. No. 5,232,701 and U.S. Pat. No. 5,208,030.

Of note is the preceding list also excluding N′-[4-[[3-[(4-chlorophenyl)methyl]-1,2,4-thiadiazol-5-yl]oxy]-2,5-dimethylphenyl]-N-ethyl-N-methylmethanimidamide. Of further note is the preceding list also excluding buthiobate, etaconazole, quinconazole, triarimol, 2-[(3-bromo-6-quinolinyl)oxy]-N-(1,1-dimethyl-2-butyn-1-yl)-2-(methylthio)acetamide, 2-[(3-ethynyl-6-quinolinyl)oxy]-N-[1-(hydroxymethyl)-1-methyl-2-propyn-1-yl]-2-(methylthio)acetamide and N-(1,1-dimethyl-2-butyn-1-yl)-2-[(3-ethynyl-6-quinolinyl)oxy]-2-(methylthio)acetamide.
Of note as fungicidal compounds in component (b) of the present composition are azoxystrobin, kresoxim-methyl, trifloxystrobin, pyraclostrobin, pyrametostrobin, pyraoxystrobin, picoxystrobin, dimoxystrobin, metominostrobin/fenominostrobin, carbendazim, chlorothalonil, quinoxyfen, metrafenone, pyriofenone, cyflufenamid, fenpropidin, fenpropimorph, bromuconazole, cyproconazole, difenoconazole, epoxiconazole, etaconazole, fenbuconazole, flusilazole, fluxapyroxad, hexaconazole, ipconazole, metconazole, myclobutanil, penconazole, propiconazole, proquinazid, prothioconazole, tebuconazole, triticonazole, famoxadone, prochloraz, penthiopyrad and boscalid (nicobifen).
Generally preferred for better control of plant diseases caused by fungal plant pathogens (e.g., lower use rate or broader spectrum of plant pathogens controlled) or resistance management are mixtures of a compound of Formula 1, an N-oxide, or salt thereof, with a fungicidal compound selected from the group: azoxystrobin, kresoxim-methyl, trifloxystrobin, pyraclostrobin, pyrametostrobin, pyraoxystrobin, picoxystrobin, dimoxystrobin, metominostrobin/fenominostrobin, quinoxyfen, metrafenone, cyflufenamid, fenpropidin, fenpropimorph, cyproconazole, difenoconazole, epoxiconazole, etaconazole, flusilazole, metconazole, myclobutanil, propiconazole, proquinazid, prothioconazole, pyriofenone, tebuconazole, triticonazole, famoxadone and penthiopyrad.
In the fungicidal compositions of the present invention, component (a) (i.e. at least one compound selected from compounds of Formula 1, N-oxides, and salts thereof) and component (b) are present in fungicidally effective amounts. The weight ratio of component (b) (i.e. one or more additional fungicidal compounds) to component (a) is generally between about 1:3000 to about 3000:1, and more typically between about 1:500 and about 500:1. Table B1 lists typical, more typical and most typical ranges of ratios involving particular fungicidal compounds of component (b). Tables A1 through A43 and C1 through C43 exemplify weight ratios for particular combinations of fungicidal compounds. Of note are compositions where in the weight ratio of component (a) to component (b) is from about 125:1 to about 1:125. With many fungicidal compounds of component (b), these compositions are particularly effective for controlling plant diseases caused by fungal plant pathogens. Of particular note are compositions wherein the weight ratio of component (a) to component (b) is from about 25:1 to about 1:25, or from about 5:1 to about 1:5. One skilled in the art can easily determine through simple experimentation the weight ratios and application rates of fungicidal compounds necessary for the desired spectrum of fungicidal protection and control. It will be evident that including additional fungicidal compounds in component (b) may expand the spectrum of plant diseases controlled beyond the spectrum controlled by component (a) alone.
Specific mixtures (compound numbers refer to compounds in Index Table A) are listed in Tables A1 through A43. In Table A1, each line below the column headings “Component (a)” and “Component (b)” specifically discloses a mixture of Component (a), which is Compound 3, with a Component (b) fungicidal compound. The entries under the heading “Illustrative Ratios” disclose three specific weight ratios of Component (b) to Component (a) for the disclosed mixture. For example, the first line of Table A1 discloses a mixture of Compound 3 with acibenzolar-S-methyl and lists weight ratios of acibenzolar-S-methyl to Compound 3 of 1:1, 1:4 or 1:18.

(*)Ratios of Component (b) relative to Component (a) by weight.
Tables A2 through A43 are each constructed the same as Table A1 above except that entries below the “Component (a)” column heading are replaced with the respective Component (a) Column Entry shown below. Thus, for example, in Table A2 the entries below the “Component (a)” column heading all recite “Compound 7”, and the first line below the column headings in Table A2 specifically discloses a mixture of Compound 7 with acibenzolar-S-methyl. Tables A3 through A43 are constructed similarly.

Table B1 lists specific combinations of a Component (b) compound with Component (a) illustrative of the mixtures, compositions and methods of the present invention. The first column of Table B1 lists the specific Component (b) compound (e.g., “acibenzolar-S-methyl” in the first line). The second, third and fourth columns of Table B1 lists ranges of weight ratios for rates at which the Component (b) compound is typically applied to a field-grown crop relative to Component (a) (e.g., “2:1 to 1:180” of acibenzolar-S-methyl relative to Component (a) by weight). Thus, for example, the first line of Table B1 specifically discloses the combination of acibenzolar-S-methyl with Component (a) is typically applied in a weight ratio between 2:1 to 1:180. The remaining lines of Table B1 are to be construed similarly. Of particular note is a composition comprising a mixture of any one of the compounds listed in Embodiment 45 as Component (a) with a compound listed in the Component (b) column of Table B1 according to the weight ratios disclosed in Table B1. Table B1 thus supplements the specific ratios disclosed in Tables A1 through A43 with ranges of ratios for these combinations.

Of note is a composition of the present invention comprising a compound of Formula 1 (or an N-oxide or salt thereof) with at least one other fungicidal compound that has a different site of action from the compound of Formula 1. In certain instances, a combination with at least one other fungicidal compound having a similar spectrum of control but a different site of action will be particularly advantageous for resistance management. Thus, a composition of the present invention can advantageously comprise at least one fungicidal active compound selected from the group consisting of (b1) through (b46) as described above, having a similar spectrum of control but a different site of action.
Compositions of component (a), or component (a) with component (b), can be further mixed with one or more other biologically active compounds or agents including insecticides, nematocides, bactericides, acaricides, herbicides, herbicide safeners, growth regulators such as insect molting inhibitors and rooting stimulants, chemosterilants, semiochemicals, repellents, attractants, pheromones, feeding stimulants, plant nutrients, other biologically active compounds or entomopathogenic bacteria, virus or fungi to form a multi-component pesticide giving an even broader spectrum of agricultural protection. Thus the present invention also pertains to a composition comprising a fungicidally effective amount of component (a), or a mixture of component (a) with component (b), and a biologically effective amount of at least one additional biologically active compound or agent and can further comprise at least one of a surfactant, a solid diluent or a liquid diluent. The other biologically active compounds or agents can also be separately formulated in compositions comprising at least one of a surfactant, solid or liquid diluent. For compositions of the present invention, one or more other biologically active compounds or agents can be formulated together with one or both of components (a) and (b) to form a premix, or one or more other biologically active compounds or agents can be formulated separately from components (a) and (b) and the formulations combined together before application (e.g., in a spray tank) or, alternatively, applied in succession.
Examples of such biologically active compounds or agents with which compositions of component (a), or component (a) with component (b), can be formulated are: insecticides such as abamectin, acephate, acetamiprid, acetoprole, acrinathrin, aldicarb, amidoflumet, amitraz, avermectin, azadirachtin, azinphos-methyl, bifenthrin, bifenazate, bistrifluoron, buprofezin, carbofuran, cartap, chinomethionat, chlorfenapyr, chlorfluazuron, chlorantraniliprole, chlorpyrifos, chlorpyrifos-methyl, chlorobenzilate, chromafenozide, clothianidin, cyantraniliprole, cyflumetofen, cyfluthrin, beta-cyfluthrin, cyhalothrin, gamma-cyhalothrin, lambda-cyhalothrin, cyhexatin, cypermethrin, cyromazine, deltamethrin, diafenthiuron, diazinon, dicofol, dieldrin, dienochlor, diflubenzuron, dimefluthrin, dimethoate, dinotefuran, diofenolan, emamectin, endosulfan, esfenvalerate, ethiprole, etoxazole, fenamiphos, fenazaquin, fenbutatin oxide, fenothiocarb, fenoxycarb, fenpropathrin, fenpyroximate, fenvalerate, fipronil, flonicamid, flubendiamide, flucythrinate, tau-fluvalinate, flufenerim, flufenoxuron, fonophos, halofenozide, hexaflumuron, hexythiazox, hydramethylnon, imicyafos, imidacloprid, indoxacarb, isofenphos, lufenuron, malathion, meperfluthrin, metaflumizone, metaldehyde, methamidophos, methidathion, methomyl, methoprene, methoxychlor, methoxyfenozide, metofluthrin, milbemycin oxime, monocrotophos, nicotine, nitenpyram, nithiazine, novaluron, noviflumuron, oxamyl, parathion, parathion-methyl, permethrin, phorate, phosalone, phosmet, phosphamidon, pirimicarb, profenofos, profluthrin, propargite, prothiocarb, protrifenbute, pymetrozine, pyrafluprole, pyrethrin, pyridaben, pyridalyl, pyrifluquinazon, pyriprole, pyriproxyfen, rotenone, ryanodine, spinetoram, spinosad, spiridiclofen, spiromesifen, spirotetramat, sulfoxaflor, sulprofos, tebufenozide, tebufenpyrad, teflubenzuron, tefluthrin, terbufos, tetrachlorvinphos, tetramethylfluthrin, thiacloprid, thiamethoxam, thiodicarb, thiosultap-sodium, tolfenpyrad, tralomethrin, triazamate, trichlorfon, triflumuron; nematocides such as aldicarb, imicyafos, oxamyl and fenamiphos; bactericides such as streptomycin; acaricides such as amitraz, chinomethionat, chlorobenzilate, cyenopyrafen, cyhexatin, dicofol, dienochlor, etoxazole, fenazaquin, fenbutatin oxide, fenpropathrin, fenpyroximate, hexythiazox, propargite, pyridaben and tebufenpyrad; and biological agents including entomopathogenic bacteria, such as Bacillus thuringiensis subsp. aizawai, Bacillus thuringiensis subsp. kurstaki, and the encapsulated delta-endotoxins of Bacillus thuringiensis (e.g., Cellcap, MPV, MPVII); entomopathogenic fungi, such as green muscardine fungus; and entomopathogenic virus including baculovirus, nucleopolyhedro virus (NPV) such as HzNPV, AfNPV; and granulosis virus (GV) such as CpGV.
General references for these agricultural protectants (i.e. insecticides, fungicides, nematocides, acaricides, herbicides and biological agents) include The Pesticide Manual, 13th Edition, C. D. S. Tomlin, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2003 and The BioPesticide Manual, 2nd Edition, L. G. Copping, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2001.
For embodiments where one or more of these various mixing partners are used, the weight ratio of these various mixing partners (in total) to component (a), or a mixture of component (a) with component (b), is generally between about 1:3000 and about 3000:1. Of note are weight ratios between about 1:100 and about 3000:1, or between about 1:30 and about 300:1 (for example ratios between about 1:1 and about 30:1). It will be evident that including these additional components may expand the spectrum of diseases controlled beyond the spectrum controlled by component (a), or a mixture of component (a) with component (b).
Component (a) compounds and/or combinations thereof with component (b) compounds and/or one or more other biologically active compounds or agents can be applied to plants genetically transformed to express proteins toxic to invertebrate pests (such as Bacillus thuringiensis delta-endotoxins). The effect of the exogenously applied present component (a) alone or in combination with component (b) may be synergistic with the expressed toxin proteins.
Of note is the combination or the composition comprising component (a), or components (a) and (b), as described in the Summary of the Invention further comprising at least one invertebrate pest control compound or agent (e.g., insecticide, acaricide). Of particular note is a composition comprising component (a) and at least one (i.e. one or more) invertebrate pest control compound or agent, which then can be subsequently combined with component (b) to provide a composition comprising components (a) and (b) and the one or more invertebrate pest control compounds or agents. Alternatively without first mixing with component (b), a biologically effective amount of the composition comprising component (a) with at least one invertebrate pest control agent can be applied to a plant or plant seed (directly or through the environment of the plant or plant seed) to protect the plant or plant seed from diseases caused by fungal pathogens and injury caused by invertebrate pests.
For embodiments where one or more of invertebrate pest control compounds are used, the weight ratio of these compounds (in total) to the component (a) compounds is typically between about 1:3000 and about 3000:1. Of note are weight ratios between about 1:300 and about 300:1 (for example ratios between about 1:30 and about 30:1). One skilled in the art can easily determine through simple experimentation the biologically effective amounts of active ingredients necessary for the desired spectrum of biological activity.
Of note is a composition of the present invention which comprises in addition to a component (a) compound, alone or in combination with component (b), at least one invertebrate pest control compound or agent selected from the group consisting of abamectin, acephate, acetamiprid, acetoprole, acrinathrin, aldicarb, amidoflumet, amitraz, avermectin, azadirachtin, azinphos-methyl, bifenthrin, bifenazate, bistrifluoron, buprofezin, carbofuran, cartap, chinomethionat, chlorfenapyr, chlorfluazuron, chlorantraniliprole, chlorpyrifos, chlorpyrifos-methyl, chlorobenzilate, chromafenozide, clothianidin, cyantraniliprole, cyflumetofen, cyfluthrin, beta-cyfluthrin, cyhalothrin, gamma-cyhalothrin, lambda-cyhalothrin, cyhexatin, cypermethrin, cyromazine, deltamethrin, diafenthiuron, diazinon, dicofol, dieldrin, dienochlor, diflubenzuron, dimefluthrin, dimethoate, dinotefuran, diofenolan, emamectin, endosulfan, esfenvalerate, ethiprole, etoxazole, fenamiphos, fenazaquin, fenbutatin oxide, fenothiocarb, fenoxycarb, fenpropathrin, fenpyroximate, fenvalerate, fipronil, flonicamid, flubendiamide, flucythrinate, tau-fluvalinate, flufenerim, flufenoxuron, fonophos, halofenozide, hexaflumuron, hexythiazox, hydramethylnon, imicyafos, imidacloprid, indoxacarb, isofenphos, lufenuron, malathion, meperfluthrin, metaflumizone, metaldehyde, methamidophos, methidathion, methomyl, methoprene, methoxychlor, methoxyfenozide, metofluthrin, milbemycin oxime, monocrotophos, nicotine, nitenpyram, nithiazine, novaluron, noviflumuron, oxamyl, parathion, parathion-methyl, permethrin, phorate, phosalone, phosmet, phosphamidon, pirimicarb, profenofos, profluthrin, propargite, protrifenbute, pymetrozine, pyrafluprole, pyrethrin, pyridaben, pyridalyl, pyrifluquinazon, pyriprole, pyriproxyfen, rotenone, ryanodine, spinetoram, spinosad, spiridiclofen, spiromesifen, spirotetramat, sulfoxaflor, sulprofos, tebufenozide, tebufenpyrad, teflubenzuron, tefluthrin, terbufos, tetrachlorvinphos, tetramethylfluthrin, thiacloprid, thiamethoxam, thiodicarb, thiosultap-sodium, tolfenpyrad, tralomethrin, triazamate, trichlorfon, triflumuron, Bacillus thuringiensis subsp. aizawai, Bacillus thuringiensis subsp. kurstaki, nucleopolyhedro viruses, encapsulated delta-endotoxins of Bacillus thuringiensis, baculoviruses, entomopathogenic bacteria, entomopathogenic viruses and entomopathogenic fungi. Of note is the aforedescribed list excluding meperflutrin, sulfoxaflor and tetramethylfluthrin.
In certain instances, combinations of a component (a) compound, alone or in mixture with component (b), with other biologically active (particularly invertebrate pest control) compounds or agents (i.e. active ingredients) can result in a greater-than-additive (i.e. synergistic) effect. Reducing the quantity of active ingredients released in the environment while ensuring effective pest control is always desirable. When synergism of invertebrate pest control active ingredients occurs at application rates giving agronomically satisfactory levels of invertebrate pest control, such combinations can be advantageous for reducing crop production cost and decreasing environmental load.
Table D1 lists specific combinations of invertebrate pest control agents with Compound 3 (identified in Index Table A) as a component (a) compound illustrative of mixtures and compositions comprising these active ingredients and methods using them according to the present invention. The second column of Table D1 lists the specific invertebrate pest control agents (e.g., “Abamectin” in the first line). The third column of Table D1 lists the mode of action (if known) or chemical class of the invertebrate pest control agents. The fourth column of Table D1 lists embodiment(s) of ranges of weight ratios for rates at which the invertebrate pest control agent is typically applied relative to Compound 3 alone or in combination with component (b) (e.g., “50:1 to 1:50” of abamectin relative to a Compound 3 by weight). Thus, for example, the first line of Table D1 specifically discloses the combination of Compound 3 with abamectin is typically applied in a weight ratio between 50:1 to 1:50. The remaining lines of Table D1 are to be construed similarly.

One embodiment of biological agents for mixing with compounds of component (a) include nucleopolyhedro virus such as HzNPV and AfNPV; Bacillus thuringiensis and encapsulated delta-endotoxins of Bacillus thuringiensis such as Cellcap, MPV and MPVII; as well as naturally occurring and genetically modified viral insecticides including members of the family Baculoviridae as well as entomophagous fungi. Of note is a composition comprising component (a) and at least one additional biologically active compound or agent selected from the Invertebrate Pest Control Agents listed in Table D1 above.
The compositions of this invention are useful as plant disease control agents. The present invention therefore further comprises a method for controlling plant diseases caused by fungal plant pathogens comprising applying to the plant or portion thereof to be protected, or to the plant seed or vegetative propagation unit to be protected, an effective amount of a composition of the invention (e.g., a composition comprising component (a), or components (a) and (b)). This aspect of the present invention can also be described as a method for protecting a plant or plant seed from diseases caused by fungal pathogens comprising applying a fungicidally effective amount of a composition of the invention to the plant (or portion thereof) or plant seed (directly or through the environment (e.g., growing medium) of the plant or plant seed).
Plant disease control is ordinarily accomplished by applying an effective amount of a composition of the invention (e.g., comprising component (a), or a mixture of components (a) and (b)), typically as a formulated composition, either pre- or post-infection, to the portion of the plant to be protected such as the roots, stems, foliage, fruit, seeds, tubers or bulbs, or to the media (soil or sand) in which the plants to be protected are growing. Component (a) or mixtures thereof can also be applied to seeds to protect the seeds and seedlings developing from the seeds. The mixtures can also be applied through irrigation water to treat plants.
Suitable rates of application (e.g., fungicidally effective amounts) of component (a) (i.e. at least one compound selected from compounds of Formula 1, N-oxides and salts thereof) as well as suitable rates of application (e.g., biologically effective amounts, fungicidally effective amounts or insecticidally effective amounts) for the mixtures and compositions comprising component (a) according to this invention can be influenced by many factors of the environment and should be determined under actual use conditions. Foliage can normally be protected when treated at a rate of from less than about 1 g/ha to about 5,000 g/ha of active ingredients. Seed and seedlings can normally be protected when seed is treated at a rate of from about 0.1 to about 10 g per kilogram of seed; and vegetative propagation units (e.g., cuttings and tubers) can normally be protected when propagation unit is treated at a rate of from about 0.1 to about 10 g per kilogram of propagation unit. One skilled in the art can easily determine through simple experimentation the application rates of component (a), and mixtures and compositions thereof, containing particular combinations of active ingredients according to this invention needed to provide the desired spectrum of plant protection and control of plant diseases and optionally other plant pests.
The compounds of Formula 1, N-oxides, and salts thereof, are particularly efficacious for controlling plant diseases caused by fungal pathogens, particularly in the Basidomycete and Ascomycete classes. Combining these compounds with other fungicidal compounds can provide control of diseases caused by a broad spectrum of fungal plant pathogens in the Basidiomycete, Ascomycete, Oomycete and Deuteromycete classes. Accordingly, mixtures and compositions described herein can control a broad spectrum of plant diseases, foliar pathogens of crops including: cereal grain crops such as wheat, barley, oats, rye, triticale, rice, maize, sorghum and millet; vine crops such as table and wine grapes; field crops such as oilseed rape (canola), sunflower; sugar beets, sugar cane, soybean, peanuts (groundnut), tobacco, alfafa, clover, lespedeza, trefoil and vetch; pome fruits such as apple, pear, crabapple, loquat, mayhaw and quince; stone fruits such as peaches, cherries, plums, apricots, nectarines and almonds; citrus fruits such as lemons, limes, oranges, grapefruit, mandarin (tangerines) and kumquat; root and tuber vegetables and field crops (and their foliage) such as artichoke, garden and sugar beet, carrot, cassaya, ginger, ginseng, horseradish, parsnip, potato, radish, rutabaga, sweet potato, turnip and yam; bulb vegetables such as garlic, leek, onion and shallot; leafy vegetables such as arugula (roquette), celery, celery, cress, endive (escarole), fennel, head and leaf lettuce, parsley, radicchio (red chicory), rhubarb, spinach and Swiss chard; brassica (cole) leafy vegetables such as broccoli, broccoli raab (rapini), Brussels sprouts, cabbage, bok Choy, cauliflower, collards, kale, kohlrabi, mustard and greens; legume vegetables (succulent or dried) such as lupin, bean (Phaseolus spp.) (including field bean, kidney bean, lima bean, navy bean, pinto bean, runner bean, snap bean, tepary bean and wax bean), bean (Vigna spp.) (including adzuki bean, asparagus bean, blackeyed pea, catjang, Chinese longbean, cowpea, crowder pea, moth bean, mung bean, rice bean, southern pea, urd bean and yardlong bean), broad bean (fava), chickpea (garbanzo), guar, jackbean, lablab bean, lentil and pea (Pisum spp.) (including dwarf pea, edible-podded pea, English pea, field pea, garden pea, green pea, snowpea, sugar snap pea, pigeon pea and soybean); fruiting vegetables such as eggplant, groundcherry (Physalis spp.), pepino and pepper (including bell pepper, chili pepper, cooking pepper, pimento, sweet pepper; tomatillo and tomato); cucurbit vegetables such as Chayote (fruit), Chinese waxgourd (Chinese preserving melon), citron melon, cucumber, gherkin, edible gourd (including hyotan, cucuzza, hechima, and Chinese okra), Momordica spp. (including balsam apple, balsam pear, bittermelon and Chinese cucumber), muskmelon (including cantaloupe and pumpkin), summer and winter squash (including butternut squash, calabaza, hubbard squash, acorn squash, spaghetti squash) and watermelon; berries such as blackberry (including bingleberry, boysenberry, dewberry, lowberry, marionberry, olallieberry and youngberry), blueberry, cranberry, currant, elderberry, gooseberry, huckleberry, loganberry, raspberry and strawberry; tree nuts such as almond, beech nut, Brazil nut, butternut, cashew, chestnut, chinquapin, filbert (hazelnut), hickory nut, macadamia nut, pecan and walnut; tropical fruits and other crops such as bananas, plantains, mangos, coconuts, papaya, guava, avocado, lichee, agave, coffee, cacao, sugar cane, oil palm, sesame, rubber and spices; fiber crops such as cotton, flax and hemp; turfgrasses (including warm- and cool-season turfgrasses) such as bentgrass, Kentucky bluegrass, St. Augustine grass, tall fescue and Bermuda grass.
These pathogens include: Oomycetes, including Phytophthora pathogens such as Phytophthora infestans, Phytophthora megasperma, Phytophthora parasitica, Phytophthora cinnamomi and Phytophthora capsici, Pythium pathogens such as Pythium aphanidermatum, and pathogens in the Peronosporaceae family such as Plasmopara viticola, Peronospora spp. (including Peronospora tabacina and Peronospora parasitica), Pseudoperonospora spp. (including Pseudoperonospora cubensis) and Bremia lactucae; Ascomycetes, including Alternaria pathogens such as Alternaria solani and Alternaria brassicae, Guignardia pathogens such as Guignardia bidwelli, Venturia pathogens such as Venturia inaequalis, Septoria pathogens such as Septoria nodorum and Septoria tritici, powdery mildew disease pathogens such as Blumeria spp. (including Blumeria graminis) and Erysiphe spp. (including Erysiphe polygoni), Uncinula necatur, Sphaerotheca fuligena and Podosphaera leucotricha, Pseudocercosporella herpotrichoides, Botrytis pathogens such as Botrytis cinerea, Monilinia fructicola, Sclerotinia pathogens such as Sclerotinia sclerotiorum, Magnaporthe grisea, Phomopsis viticola, Helminthosporium pathogens such as Helminthosporium tritici repentis, Pyrenophora teres, anthracnose disease pathogens such as Glomerella or Colletotrichum spp. (such as Colletotrichum graminicola and Colletotrichum orbiculare), and Gaeumannomyces graminis; Basidiomycetes, including rust diseases caused by Puccinia spp. (such as Puccinia recondite, Puccinia striiformis, Puccinia hordei, Puccinia graminis and Puccinia arachidis), Hemileia vastatrix and Phakopsora pachyrhizi; other pathogens including Rhizoctonia spp. (such as Rhizoctonia solani and Rhizoctonia oryzae); Fusarium pathogens such as Fusarium roseum, Fusarium graminearum and Fusarium oxysporum; Verticillium dahliae; Sclerotium rolfsii; Rynchosporium secalis; Cercosporidium personatum, Cercospora arachidicola and Cercospora beticola; Rutstroemia floccosum (also known as Sclerontina homoeocarpa); and other genera and species closely related to these pathogens. Commonly, pathogens are referred to as diseases, and thus in the preceding sentence the word “pathogen” also refers to the plant disease caused by the pathogen. More precisely, plant diseases are caused by pathogens. Therefore, for example, powdery mildew diseases are plant diseases caused by powdery mildew pathogens, Septoria diseases are plant diseases caused by Septoria pathogens, and rust diseases are plant diseases caused by rust disease pathogens. Certain fungicidal compounds are also bactericidal, and therefore in addition to their fungicidal activity, the compositions or combinations can also have activity against bacteria such as Erwinia amylovora, Xanthomonas campestris, Pseudomonas syringae, and other related species.
Remarkably, 2,6-substituted aniline-pyrazole compounds of Formula 1 (i.e. Formula 1 wherein X is NH, and R1 and R3 are other than H) wherein R2 is H have now been discovered to have significantly improved pharmacokinetic properties compared to corresponding compounds wherein R2 is other than H. In particular in vertebrate animals, compounds wherein R2 is H instead of other than H have been found to have a significantly diminished distribution into fat, thereby reducing the possibility of bioaccumulation. Illustrative of 2,6-substituted aniline-pyrazole compounds of Formula 1 wherein R2 is H are Compounds 239, 240, 241, 244, 245, 247, 252, 253, 254, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 273, 275 and 276 identified in Index Table A. Furthermore, in addition to having more favorable pharmacokinetic properties in vertebrate animals, 2,6-substituted anilino-pyrazole compounds of Formula 1 wherein R1 is halogen, or more particularly Cl or Br, and R3 is F or Cl, or more particularly F, have been discovered to retain remarkably high activity when R2 is H against plant fungal diseases, such as caused by Septoria tritici.
The pharmacokinetic properties of compounds of Formula 1 can be measured using a wide variety of assay protocols known in the science of pharmacology. In one illustrative method involving a single oral dose, three male and three female rats receive a single dose of a test substance via oral gavage. Approximately 0.25 mL of blood is collected via tail vein immediately prior to dosing, and then at 0.25, 0.5, 1, 2, 4, 8, 12, 24 h and every 24 h thereafter until sacrifice. At sacrifice, fat is also collected to determine the fat:plasma ratio at sacrifice. Blood is collected into tubes that contain ethylenediaminetetracetic acid (EDTA) and centrifuged at 2500×g in order to separate plasma from blood cells. The plasma is then extracted by protein precipitation using, for example, acetonitrile and a protein precipitation plate (e.g., Strata Impact Protein Precipitation Plate, part number CEO-7565 of Phenomenex, Torrance, Calif., U.S.A.) following directions provided for the plate. Alternatively, the plasma is extracted just with acetonitrile, vortexed (i.e. mixed using a vortex mixer), and centrifuged to pellet the proteins. After removal of the proteins, the plasma is analyzed for parent compound and/or metabolites by liquid chromatography-mass spectrometry (LC/MS). The fat is homogenized and extracted by an organic solvent such as acetonitrile. The extract is then analyzed for parent compound and/or metabolites by LC/MS. The plasma pharmacokinetic data is then analyzed using nonlinear modeling software (e.g., WinNonlin™ from Pharsight, Cary, N.C., U.S.A.) to determine half-life of the administered compound in plasma, the time after administration when the maximum plasma concentration is reached (Tmax), the maximum plasma concentration (Cmax) and the area under the plasma concentration curve (AUC). As analysis of fat requires rat sacrifice, fat data is obtained at single time points (i.e. the time of rat sacrifice). However, by using multiple rats sacrificed after different intervals from time of dosing, such parameters as Cmax for fat are determined. Using the above described method, Compounds 239, 240 and 241 identified in Index Table A are found to have a significantly diminished distribution into fat compared to corresponding compounds wherein R2 is other than H.
In the present fungicidal compositions, the Formula 1 compounds of component (a) can work synergically with the additional fungicidal compounds of component (b) to provide such beneficial results as broadening the spectrum of plant diseases controlled, extending duration of preventative and curative protection, and suppressing proliferation of resistant fungal pathogens. In particular embodiments, compositions are provided in accordance with this invention that comprise proportions of component (a) and component (b) that are especially useful for controlling particular fungal diseases (such as Alternaria solani, Blumeria graminis f. sp. tritici, Botrytis cinerea, Puccinia recondite f. sp. tritici, Rhizoctonia solani, Septoria nodorum, Septoria tritici).
Mixtures of fungicides may also provide significantly better disease control than could be predicted based on the activity of the individual components. This synergism has been described as “the cooperative action of two components of a mixture, such that the total effect is greater or more prolonged than the sum of the effects of the two (or more) taken independently” (see P. M. L. Tames, Neth. J. Plant Pathology 1964, 70, 73-80). In methods providing plant disease control in which synergy is exhibited from a combination of active ingredients (e.g., fungicidal compounds) applied to the plant or seed, the active ingredients are applied in a synergistic weight ratio and synergistic (i.e. synergistically effective) amounts. Measures of disease control, inhibition and prevention cannot exceed 100%. Therefore expression of substantial synergism typically requires use of application rates of active ingredients wherein the active ingredients separately provide much less than 100% effect, so that their additive effect is substantially less than 100% to allow the possibility of increase in effect as result of synergism. On the other hand, application rates of active ingredients that are too low may show not show much activity in mixtures even with the benefit of synergism. One skilled in the art can easily identify and optimize through simple experimentation the weight ratios and application rates (i.e. amounts) of fungicidal compounds providing synergy.
The following Tests include tests demonstrating the efficacy of the present compounds for controlling specific pathogens; this efficacy is thus provided to fungicidal mixtures comprising the present compounds. The following Tests also include tests demonstrating the control efficacy of the mixtures of this invention on specific pathogens. The disease control afforded by the present compounds alone or in mixtures is not limited, however, to the pathogenic fungi species exemplified.
See Index Table A for compound descriptions. See Index Table B for melting point data. See Index Table C for 1H NMR data. The following abbreviations are used in the Index Tables which follow: Me is methyl, MeO is methoxy, EtO is ethoxy, and —CN is cyano. Because of symmetry, R1 can be interchanged with R3, and R4 can be interchanged with R6, if allowed by the definitions of R1, R3, R4 and R6. The abbreviation “Cmpd.” stands for “Compound”, and the abbreviation “Ex.” stands for “Example” and is followed by a number indicating in which Synthesis Example the compound is prepared. Mass spectra (M.S.) are reported as the molecular weight of the highest isotopic abundance parent ion (M+1) formed by addition of H+ (molecular weight of 1) to the molecule, observed by mass spectrometry using atmospheric pressure chemical ionization (AP+). The presence of molecular ions containing one or more higher atomic weight isotopes of lower abundance (e.g., 37Cl, 81Br) is not reported.

General protocol for preparing test suspensions for Tests A-I: the test compounds were first dissolved in acetone in an amount equal to 3% of the final volume and then suspended at the desired concentration (in ppm) in acetone and purified water (50/50 mix by volume) containing 250 ppm of the surfactant Trem® 014 (polyhydric alcohol esters). The resulting test suspensions were then used in Tests A-I. Each test was conducted in triplicate, and the results were averaged. Spraying a 200 ppm test suspension to the point of run-off on the test plants was the equivalent of a rate of about 800 g/ha. Unless otherwise indicated, the rating values indicate a 200 ppm test suspension was used. (An asterisk “*” next to the rating value indicates a 40 ppm test suspension was used.)
The test suspension was sprayed to the point of run-off on tomato seedlings. The following day the seedlings were inoculated with a spore suspension of Botrytis cinerea (the causal agent of tomato Botrytis) and incubated in saturated atmosphere at 20° C. for 48 h, and then moved to a growth chamber at 24° C. for 3 additional days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on tomato seedlings. The following day the seedlings were inoculated with a spore suspension of Alternaria solani (the causal agent of tomato early blight) and incubated in a saturated atmosphere at 27° C. for 48 h, and then moved to a growth chamber at 20° C. for 5 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on tomato seedlings. The following day the seedlings were inoculated with a spore suspension of Phytophthora infestans (the causal agent of tomato late blight) and incubated in a saturated atmosphere at 20° C. for 24 h, and then moved to a growth chamber at 20° C. for 5 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on creeping bent grass (Agrostis sp.) seedlings. The following day the seedlings were inoculated with a bran and mycelial slurry of Rhizoctonia solani (the causal agent of turf brown patch) and incubated in a saturated atmosphere at 27° C. for 48 h, and then moved to a growth chamber at 27° C. for 3 days, after which time disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria nodorum (the causal agent of Septoria glume blotch) and incubated in a saturated atmosphere at 24° C. for 48 h, and then moved to a growth chamber at 20° C. for 9 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria tritici (the causal agent of wheat leaf blotch) and incubated in saturated atmosphere at 24° C. for 48 h. and then the seedlings were moved to a growth chamber at 20° C. for 19 additional days, after which time visual disease ratings were made.
Wheat seedlings were inoculated with a spore suspension of Puccinia recondita f. sp. tritici (the causal agent of wheat leaf rust) and incubated in a saturated atmosphere at 20° C. for 24 h, and then moved to a growth chamber at 20° C. for 2 days. At the end of this time the test suspension was sprayed to the point of run-off, and then the seedlings were moved to a growth chamber at 20° C. for 4 days after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Puccinia recondita f. sp. tritici (the causal agent of wheat leaf rust) and incubated in a saturated atmosphere at 20° C. for 24 h, and then moved to a growth chamber at 20° C. for 6 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore dust of Blumeria graminis f. sp. tritici (also known as Erysiphe graminis f. sp. tritici, the causal agent of wheat powdery mildew) and incubated in a growth chamber at 20° C. for 8 days, after which time visual disease ratings were made.
Results for Tests A-I are given in Table A. In the Table, a rating of 100 indicates 100% disease control and a rating of 0 indicates no disease control (relative to the controls). A hyphen (-) indicates no test results.

Compound 81, bixafen, 5-chloro-6-(2,4,6-trifluorophenyl)-7-(4-methylpiperidin-1-yl)[1,2,4]triazolo[1,5-a]pyrimidine (BAS600), cyproconazole, isopyrazam, penthiopyrad, probenazole, quinoxyfen and spiroxamine were obtained as unformulated, technical-grade materials. Azoxystrobin, boscalid, chlorothalonil, copper hydroxide, cymoxanil, difenoconazole, dimethomorph, epoxiconazole, fenpropimorph, fluazinam, fludioxonil, folpet, iprodione, iprovalicarb, mancozeb, mefenoxam (also known as metalaxyl-M), myclobutanil, picoxystrobin, proquinazid, prothioconazole, pyraclostrobin, tetraconazole and tricyclozole were obtained as formulated products marketed under the trademarks AMISTAR, ENDURA, BRAVO, KOCIDE, CURZATE, SCORE, ACROBAT, OPUS, CORBEL, OMEGA, MAXIM, PHALTAN, ROVRAL, MELODY, MANZATE, RIDOMIL GOLD, NOVA, ACANTO, TALIUS, PROLINE, HEADLINE, DOMARK and BEAM, respectively. Unformulated materials were first dissolved in acetone and then suspended at the desired concentration (in ppm) in acetone and purified water (50/50 mix by volume) containing 250 ppm of the surfactant Trem® 014 (polyhydric alcohol esters). Formulated materials were dispersed in sufficient water to give the desired concentration, and neither organic solvent nor surfactant was added to the suspension. The resulting test mixtures were then used in Tests K, L and M. Spraying a 200 ppm test suspension to the point of run-off on the test plants was the equivalent of a rate of about 800 g/ha. The tests were replicated three times and the results reported as the mean average of the three replicates.
The presence of a synergistic effect between two active ingredients was established with the aid of the Colby equation (see Colby, S. R. “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations”, Weeds, (1967), 15, 20-22):
Using the method of Colby, the presence of a synergistic interaction between two active ingredients is established by first calculating the predicted activity, p, of the mixture based on activities of the two components applied alone. If p is lower than the experimentally established effect, synergism has occurred. In the equation above, A is the fungicidal activity in percentage control of one component applied alone at rate x. The B term is the fungicidal activity in percentage control of the second component applied at rate y. The equation estimates p, the expected fungicidal activity of the mixture of A at rate x with B at rate y if their effects are strictly additive and no interaction has occurred.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore dust of Blumeria graminis f. sp. tritici, (also known as Erysiphe graminis f. sp. tritici, the causal agent of wheat powdery mildew) and incubated in a growth chamber at 20° C. for 7 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Puccinia recondite f. sp. tritici (the causal agent of wheat leaf rust) and incubated in a saturated atmosphere at 20° C. for 24 h, and then moved to a growth chamber at 20° C. for 6 days, after which time visual disease ratings were made.
The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria tritici (the causal agent of wheat leaf blotch) and incubated in saturated atmosphere at 24° C. for 48 h. and then the seedlings moved to a growth chamber at 20° C. for 19 additional days, after which time visual disease ratings were made.
Results for Tests K-M are presented in the following Tables B through K. A rating of 100 indicates 100% disease control and a rating of 0 indicates no disease control (relative to the controls). A dash (-) indicates no test results. Columns labeled “Obsd” indicate the average of results observed from three replications. Columns labeled “Exp” indicate the expected effect for each treatment mixture calculated using the Colby Equation.

Tables B through K show compositions of the present invention comprising mixtures of a representative Formula 1 compound with a variety of component (b) compounds demonstrating, in some instances, synergistic control of wheat powdery mildew, leaf rust, and leaf blotch. As control cannot exceed 100%, increased activity above expected fungicidal activity was not always observed in mixtures but more likely observed when the separate active ingredient components alone were at application rates providing considerably less than 100% control. Synergy may not be evident at low application rates where the individual active ingredient components alone have little activity. However, in some instances greater activity was observed for combinations wherein individual active ingredients alone at the same application rates had little or no activity. As demonstrated above, this invention provides a method for controlling powdery mildew (Blumeria graminis f. sp. tritici), leaf rust (Puccinia recondite f. sp. tritici), and wheat leaf blotch (Septoria tritici).
Tests N1 and N2 involved evaluation of mixtures of Compound 81 with 2-[(3-bromo-8-methyl-6-quinolinyl)oxy]-N-(1,1-dimethyl-2-propyn-1-yl)-2-(methylthio)acetamide (Compound A1) and 2-[(3-bromo-6-quinolinyl)oxy]-N-(1,1-dimethylethyl)butanamide (Compound A2), respectively, for inhibiting the growth of Septoria tritici (the causal agent of wheat leaf blotch). The general protocol for preparing test compositions was as follows. Compound 81 (Tests N1 and N2), Compound A1 (Test N1) and Compound A2 (Test N2) were obtained as unformulated, technical-grade materials. Unformulated test compounds were first dissolved in DMSO at the appropriate concentration to provide the desired concentration (in μM) after mixing with the fungal growth medium in the wells of 96-well plates containing 200 μL fungal growth medium per well. The ranges of compound concentrations were chosen to span a range of inhibitory activity from 0 to near 100% to identify any synergistic action when Septoria tritici was treated with compounds added in combination. The DMSO solutions of the test compounds were added to the wells prior to addition of the fungal growth medium.
The fungal growth solid medium was prepared by forming an aqueous mixture containing dipotassium hydrogen phosphate (3.0 g/L), potassium dihydrogen phosphate (4.0 g/L), sodium chloride (0.5 g/L), ammonium chloride (1.0 g/L), magnesium sulfate heptahydrate (0.2 g) and calcium chloride dihydrate (0.01 g/L), also containing 1 mL/L of a trace element solution (manganese sulfate hydrate (0.1 mg/mL), zinc sulfate heptahydrate (0.2 mg/mL), copper(II) sulfate pentahydrate (0.2 mg/mL), iron(II) sulfate heptahydrate (0.2 mg/mL), sodium molybdate dihydrate (0.1 mg/mL), cobalt(II) sulfate heptahydrate (0.06 mg/mL), boric acid (0.08 mg/mL)), and supplemented with 50 μL/L of a biotin stock solution (0.1 mg/mL). The pH was adjusted to 6.8 with aqueous 1 M sodium carbonate solution. The mixture was further supplemented with 1 g/L of yeast extract, and GELRITE gellan gum (Kelco) (4 g/L) was added. Sufficient water was added to bring the volume to 90% of final volume (e.g., 900 mL volume for preparation of 1 L of fungal growth medium). The mixture was autoclaved. On cooling to 60° C., 100 mL/L of aqueous dextrose solution (10 g/L), 500 μL/L of aqueous ampicillin solution (100 mg/mL) and 500 μL of rifampicin solution (10 mg/mL in DMSO) were added to provide the final volume of fungal growth medium, which was then dispensed while still warm using a microliter pipette to the wells of the 96-well plates. The dispensed fungal growth medium in each well was agitated using the tip of the dispensing pipette to mix it with the DMSO solution containing the test compounds.
After the fungal growth medium in the wells had cooled to room temperature and solidified, the top surface of the growth medium in each well was inoculated with 20 μL of a suspension of fungus containing 8×104 cells. Following a 2 h period of drying in a sterile hood, plates were placed in a dark incubator at 25° C. for 5 d.
Fungal growth was assessed on a plate reader set to measure absorbance of 600 nm light. The percent growth inhibition observed (Obsd.) in Tests N1 and N2, as well as the percent growth inhibition expected (Exp.) from calculation using the Colby equation, are listed in Tables L and M, respectively.

The observed and expected results from mixtures of Compound 81 with Compound A1 in Test N1 presented in Table L show greater than expected activity (i.e. synergy) at application rates wherein Compound 81 and Compound A1 separately provide much less than 100% inhibition (to allow expression of synergistic increase in inhibition) but also wherein the application rates are not greatly reduced from the application rates providing high inhibition by Compounds 81 and Compound A1 separately (e.g., application rates of 0.008 or 0.016 μM of Compound 81 and an application rate of 0.008 μM of Compound A1). Similarly, the observed and expected results from mixtures of Compound 81 with Compound A2 in Test N2 presented in Table M show greater than expected activity at application rates wherein Compound 81 and Compound A2 separately provide much less than 100% inhibition but also wherein the application rates are not greatly reduced from the application rates providing high inhibition by Compounds 81 and Compound A2 separately (e.g., application rates of 0.008 or 0.016 μM of Compound 81 and an application rate of 0.8 μM of Compound A2).
